-ism, -ismus

aseism, aseismic
1. Resistant to the destructive effects of earthquakes.
2. No earthquake; without shaking (as exists with an earthquake).

Data on hydroseisms in wells are published annually by the U.S. Coast and Geodetic Survey.

Fault slips include aseismic creep and transient slip

Slip on faults occurs as a combination of relatively continuous aseismic creep and transient slip events. These transient events occur as earthquakes radiating seismic waves, and also as aseismic events with characteristic time scales of days to years.

A better understanding of the physical factors that control the relative amount and location of seismic and aseismic slip is a key goal in the study of fault mechanics and, in particular, can affect assessments of reginal seismic and tsunami hazards.

asepticism (s) (noun) (no plural)
1. Free from living germs of disease, fermentation, or putrefaction; sterile: The fermentation barrels were kept in a state of asepticism in order to maintain the high quality and safety of the wine.
2. Designed to prevent infection from pathogenic microorganisms: Ted, the health practitioner, taught the homeless people some basic lessons in asepticism in order to help them maintain better health.
3. Free of pathogenic microbes: An asepticism of surgical instruments and environment is always a major objective of hospitals.
4. Using methods to protect against infection by pathogenic microorganisms: Dr. Payne insists on preparing a condition of asepticism for patients before any surgical procedures take place.
5. Lacking animation or emotion: Jim's facial asepticism was difficult to maintain all the time while the seals were performing at the aquarium.
assimilationism (s) (noun), assimilationisms (pl)
The practice or policy of encouraging the integration of people from all races and cultures: "At first the family from Iraq resisted the assimilationism of the United States."
asterism
1. In astronomy, a cluster of stars (or a small constellation).
2. In mineralogy, a six-rayed star-shaped figure seen in some crystal structures under reflected or transmitted light.
3. Etymology: from Greek asterismos, from asterizein, "to arrange in constellations"; from aster-, "star".
astigmatism (s) (noun), astigmatisms (pl)
1. A defect in a lens of an eye that prevents light rays from meeting at a single point, thus producing an imperfect image.
2. A common form of visual impairment in which part of an image is blurred, due to an irregularity in the curvature of the front surface of the eye, the cornea.

The curve of the cornea is shaped more like an American football or a rugby ball rather than normally as a spherical basketball.

Light rays entering the eye are not uniformly focused on the retina; resulting in blurred vision at all distances and only part of what a person is looking at is in clear focus at any one time.

3. Etymology: coined in form of astigmatic in 1849 by English scientist William Whewell (1794-1866), from Greek a-, "without" + stigmatos, stigma, "a mark, a spot, a puncture".
astrobolism
The result of being struck by a star.

Supposedly, the star is Sirius, the dog star; because it rises and sets with the sun during summer in the northern hemisphere, its name is associated with "dog days" usually applicable to the hottest part of the year in places north of the equator.

The dog days are those from about the middle of July to the middle of August although the exact dates vary depending on where people live.

The thought behind astrobolism was connected to an old idea that this period of summer was under a bad influence, in which dogs ran mad, the air was unwholesome, sunstroke was common, and practical work was not done because of a lack of desire by people to do anything.

atavism (s) (noun), atavisms (pl)
1. The emergence of a genetic characteristic typical of a previous generation, which could be caused by a recombination of genes: Some people have the impression that James is reverting to atavisms that existed when he was a child.
2. The reappearance of a former behavior even after a long period of being educated or trained: Mark's dog seemed to be returning to a kind of atavism which it had when it was a wild dog.
3. Etymology: from French atavisme; from Latin atavus, "ancestor, forefather"; from at- perhaps here meaning "beyond" + avus, "grandfather"; from "adult male relative other than the father".
A little boy is behaving like a monkey swinging from the ceiling light.

augurism
autism
1. Mental introversion in which the attention or interest is fastened on the patient's own ego; a self-centered mental state from which reality tends to be excluded.
2. A mental disorder characterized by severely abnormal developments of social interaction and verbal and nonverbal communication skills.
3. A tendency to view life in terms of one's own needs and desires.

Affected individuals may adhere to inflexible, nonfunctional rituals or routine. They may become upset with even trivial changes in their environment. They often have a limited range of interests but may become preoccupied with a narrow range of subjects or activities. They appear unable to understand others' feelings and often have poor eye contact with others.

Unpredictable mood swings may occur. Many demonstrate stereotypical motor mannerisms; such as, hand or finger flapping, body rocking, or dipping. The disorder is probably caused by organically based central nervous system dysfunction, especially in the ability to process social or emotional information or language.

autocatheterism

autochthonism
1. Originating where found; indigenous: autochthonous rocks; an autochthonous people; autochthonous folktales.
2. In biology, originating or formed in the place where found: an autochthonous blood clot.
autocratism (s) (noun), autocratisms (pl)

automatism
1. Behavior that is not under the control of the will, as a reflexive response.
2. An apparently goal-directed activity that is not, in fact, under the conscious, voluntary control, of the subject (occurring in epilepsy, catatonia, and fugue states).

This subject includes the performance of acts without conscious will, as, for example, after an attack of epilepsy or a concussion of the brain.

In such conditions, the person may perform acts of which he or she is neither conscious of at the time nor has any memory afterwards.

It is especially liable to occur when people suffering from epilepsy, mental subnormality, or concussion consume alcoholic drinks.
